1970 Mustang Restomod Update

[bherman]

Hi All, Rick A.K.A. Friar Tuck asked in a prior post how the Mustang project was going. Bob has been working on the Mustang and this is a progress report.

The shock tower brace is machined and the export brace portion is in process. The export brace will attach to the center of the tower brace and attach to the center of the cowl. The diagonal braces on the bottom of the frame rails mount the sway bar and support/mount the radiator. The NASCAR style radiator is multiple path with an integral oil cooler, Bob's hoping that it will cool the supercharged 4.6 liter.

The package is tight for the header tubes and Bob elected to build the manifolds in a unequal length configuration as opposed to a tuned length header. He felt that there was little performance advantage of the longer tuned header on the supercharged engine and the "shorty" style placed the collector in a better location. This will allow him to keep the exhaust "tucked" up in the chassis for good clearance.

We will continue the progress reports as things happen.

Hi Brian,

Keep the pictures coming. :-D I guess you solid model all of those new chassis and power updates in your favorite Solid Modeling CAD program and then have everything laser cut and CNC machined all from the design files you created.

Can you imagine some of the people on this group think that CAD SolidModeling is an expensive toy and a waste of time to talk about! :shock::shock::shock: I hope they are in the minority, sounds like they are advocating a Luddite arguement to me.:shock:

I guess your new beautiful ewheel was made with the same program and process.

Keep up the great work and thanks for sharing!! The designs you guys are coming up with are stunning.

Wray,

I had to look up the new word. Thanks for stretching my knowledge.

Luddite –



From Wikipedia, the free encyclopedia

Jump to: navigation, search

"The Luddites were a social movement of English workers in the early 1800s who protested – often by destroying textilemachines – against the changes produced by the Industrial Revolution that they felt threatened their jobs. The movement, which began in 1811, was named after a probably mythical leader, Ned Ludd. For a short time the movement was so strong that it clashed in battles with the British Army. Measures taken by the government included a mass trial at York in 1813 that resulted in many death penalties and transportations (deportment to a penal colony).

The English historical movement has to be seen in its context of the harsh economic climate due to the Napoleonic Wars; but since then, the term Luddite has been used to describe anyone opposed to technological progress and technological change. For the modern movement of opposition to technology, see neo-luddism."

HI Wray, Yeah, solid modeling is changing the way we do even our personal projects. Tony Dunlop, an associate of Bob's, modeled three or four variants of the shock tower brace before he and Bob liked the result. Modeling has the advantage of allowing you to take "uglies" out prior to fabrication or machining.

Bob's time to work on his projects is very limited, computor modeling is another step in the project, but it ultimately saves time. The ability to do your packaging work in 3D is invaluable. When the models are completed you can use them to do laser cutting, CNC machining and a host of other processes without creating a drawing. On sheet metal parts it allows you to unfold an accurate pattern, a real time saver!

I never really thought about the "Information Package" the way you present it, but ultimately that's the largest gain from modeling your project.

Wray, thanks for your kind comments.

Hi Brian, the `stang is looking killer. Question on the solid modeling. Bob had a friend Tony do the solid modeling work for him, correct? Was it necessary for Bob to know all the capabilities of the program to get the design he wanted, or did he just tell Tony what he wanted and then choose?

I agree that solid modeling is here and now a great way way to design things. Would it be necessary for a guy wanting to learn metalshaping to buy and learn a solid modeling program before he learns to shrink and stretch metal? I mean the new guys just joining this list or coming to a Meet.

I, like Bob have a number of friends that have CAD skills and they design, or transfer my drawings into drawings and CAM programs to enable me to have parts built. I do work for them also, so I find it easier to use their specialized skill set than develop my own.

Bob and Tony really outdid themselves on the "monte carlo bar". The whole car is a work of art so far.........john

Hey Brian,

Looks awesome and it looks like you managed adding pics too!!! CONGRATS!

Hi John, As with any tool or process one has to determine if it meets with the requirements of the application. I like to think of each new skill set that I acquire (or attempt to acquire) as a new building block. As the pile of blocks gets larger so do your capabilities and flexibility.

When we start, we learn the basic skills, cut, bend and weld. Then we start adding new skills, shrinking, stretching, hammer forming, compound forming, spinning, ect. Hopefully with time and experience we refine these skills until we have a capability larger than the sum of the individual skills.

I also believe that some new skills add to the total exponentially. CAD allows many functions that may not be apparent on the surface. The ability to cut and machine components from the model is only a small portion of its true capability. Accurate weight of components and assemblies and their center of mass is invaluable (what is the front and rear weight of this chassis?). With the correct software you can determine where your structure is highly stressed and take corrective action. This is just a small portion of CADs capabilities I have used.

Bob utilizes CAD data daily in his business, Tony works for Bob and while Bob may not be a proficient as Tony with CAD, He understands the process very well.

Would I start with CAD to learn shaping skills? No, but I wouldn't try to learn shaping without having a number of other skills, first.

Hi Brian,

Just curious....were the headers modeled in CAD prior to cutting/welding, etc?

In my shop we made an atmospheric chamber for a customer with SS piping almost as complicated as your headers. By modeling the piping, rather than the usual trial and error fitting, everything could be cut to exact size for welding. And the best part is it fit perfectly the first time.

Hi Brian, thanks for the photo update. It's coming along great. You guys have come a long way since we talked. I'm curious what Solid Modeling software that Bob and Tony use. The headers are great, and I agree that Bob really wouldn't gain a whole lot with tuned headers, so I think he's made a good call, mostly considering the space challenges being faced. I know how tight the Mustang unibodies were, and there just ain't much to play with. Kudos, keep the pictures coming.

Tuck,
